Triggering of the muscle action potential occurs after Ach binds to chemically gated channels in the motor end plate membrane. Acetylcholine (Ach) is a neurotransmitter produced by nerve cells.
An action potential is an electrical signal that travels along the cell membrane as a wave.
This action potential (muscle action potential) drives the contraction of muscle fibers.
When the action potential reaches the neuromuscular junction (i.e., the motor end-plate), acetylcholine (Ach) is released into the synaptic cleft.
Subsequently, Ach can bind and open specific channels localized on the surface of the muscle cells, thereby depolarizing them and triggering muscle contraction.

The same principle apply to stereo microscopes, a 10X eye piece combined with a 4X objective lens will produce 40X magnification.
Answer:
True
Explanation:
Conscientiousness is a human trait that internalizes.
A water molecule is an example of a compound.
It is NOT a mixture because it is not a combination of 2 or more substances.
It is NOT an element because water is composed of two different elements, those being 2 atoms of hydrogen and 1 atom of oxygen.
It is NOT an atom because water is composed of 2 hydrogen atoms and 1 oxygen atom.
It IS a compound because it is composed of two different elements.
